Disadvantages of Linked Lists
- Random Access: Unlike arrays, linked lists do not allow direct access to elements by index. Traversal is required to reach a specific node.
- Extra Memory: Linked lists require additional memory for storing the pointers, compared to arrays.
Understanding the basics of Linked List
Linked List is a linear data structure, in which elements are not stored at a contiguous location, rather they are linked using pointers. Linked List forms a series of connected nodes, where each node stores the data and the address of the next node.
Node Structure: A node in a linked list typically consists of two components:
Data: It holds the actual value or data associated with the node.
Next Pointer: It stores the memory address (reference) of the next node in the sequence.
Head and Tail: The linked list is accessed through the head node, which points to the first node in the list. The last node in the list points to NULL or nullptr, indicating the end of the list. This node is known as the tail node.
